Antioxidant Activity in Se-Enriched Edible Mushrooms
Abstract: Mushrooms enriched with essential minerals, such as selenium (Se), are food that compensate for dietary nutrient deficiencies. Extracts from Se-enriched Pleurotusostreatus and Lentinula edodes mushrooms contain active antioxidant compounds, which enhance the immune system. To evaluate whether Se-enrichment changes antioxidant and lipid peroxidation potential, the concentration of total phenolic compounds, antioxidant activity, lipid peroxidation and the total concentration of minerals (Mn, Fe, Cu, Zn, V, Cr, Co, Ni, As, Cd …

Synthesis, Characterization, and Biomedical Applications of a Silver Nanoparticle-Coated Chitosan–Fucoidan–Polymer Nanocomposite Loaded with Persea americana Leaf Extract
Abstract: Consuming a natural composite of Persea americana (Avocado) leaf extract and a chitosan and fucoidan form a biodegradable biopolymer matrix–polymer nanocomposite with biomedical applications, this study explored a potential therapeutic method. GC–MS and UV spectroscopy were used to describe the aqueous leaf extract, which was verified by phytochemical screening to contain flavonoids, tannins, phenols, terpenoids, and alkaloids. The chitosan–fucoidan biodegradable polymer matrix served as a biocompatible stabilizing and encapsulating carrier …

Glutathione peroxidase (GPx) in Breast Carcinoma
Abstract: Cancer is one of the significant problem from health perspective, every year many females are diagnosed with breast cancer out of which many die because of this disease worldwide. Oxidative stress in human body is a result of imbalance between free radical production and antioxidant defense which may result in carcinogenesis. Primary defense Primary defenses rely on the direct scavenging and inactivation of the reactive oxygen species (ROS) which includes …

Evaluation of Antioxidant Activity of Coumarin Isolated from Eupatorium triplinerve
Abstract: Eupatorium triplinerve (Asteraceae) is a slender herb with narrow lanceolate leaves. Extract of the plant is used as antiseptic, and in the treatment of various ulcers and haemorrhages. Ayapana is a rich source of naturally occurring coumarin chemicals. Coumarins are chemical compounds found in many plants and which usually have a sweet scent—much like newly-mown hay. Coumarin has clinical value as the precursor for several anticoagulant drugs; most notably, one …

Exploring the Therapeutic Potential of Phytohormones: Bridging Plant Immunity and Human Health
Abstract: This review highlights the multifaceted roles of phytohormones, including salicylic acid, abscisic acid, cytokinins, and brassinosteroids, emphasizing their contributions to plant immunity and potential therapeutic applications in human health. Phytohormones are critical regulators of plant growth, development, and defense, functioning as signaling molecules that activate and coordinate plant responses to biotic and abiotic stresses. Salicylic acid, in particular, is instrumental in systemic acquired resistance (SAR), a defense mechanism that strengthens …

Molecular Mechanism of Fluoride Induced Oxidative Stress and Its Possible Reversal by Chelation Therapy
Abstract: Fluorine (Fl) a member of the halogen family is the most electronegative and reactive of all the elements of the Periodic table. Chronic and acute exposures of fluoride leads to cardiovascular disease (hypertension and atherosclerosis), neurological disorders, gastrointestinal disturbances, liver disease, renal disease, reproductive effects, other health disorders and also affects the antioxidant system in the body. Furthermore, reactive oxygen species (ROS)-mediated oxidative damage is a common malady in fluoride …

Review on Histological Effect of Lead on Liver and Kidney
Abstract: Our environment can be polluted by environmental toxins which are chemicals and other materials produced largely from industry and its products. There are large numbers of environmental toxicants which are potentially harmful to health. These large numbers of environmental toxicants can be divided into three major categories (heavy metals, air pollutants, and pesticides) and they are commonly studied environmental toxicants. Environmental toxins can be entered into the body by various …

Effect of Vidarikand (Extracts) on Oxidative Stability of Ghee: A Comparative Study
Abstract: Antioxidant activities of vidarikand (Pueraria tuberosa) extracts were evaluated and compared with BHA, TBHQ, rosemary and green tea using a β-carotene bleaching assay, a 2, 2-diphenyl-β-picrylhydrazyl (DPPH) assay and the Rancimat method. Phenolic content and antioxidant activity (β-carotene–linoleic acid model system and DPPH assay) of ethanolic extract of vidarikand was more compared to its aqueous extract. Ethanolic extract of the vidarikand was more effective in preventing the development of the …

Studies on Different Qualitative Traits of Green Tea Grown in Nontraditional Area Processed by Oven Drying and Microwave Drying in Different Power Levels
Abstract: In this study, tea plants (Camellia sinensis L.) were grown in nontraditional region with different soil and climatic characteristics in the southern part of West Bengal. To study the effect of different drying methods for production of green tea is main focus of this paper. Green tea is produced by applying nominal heat treatment targeting to inactivate the polyphenol oxidase and peroxidase enzymes to retain the original polyphenol content. Therefore, …

Nitric Oxide—An Important Biomolecule in Breast Carcinoma
Abstract: Breast cancer represents significant problem of the world. Reactive nitrogen species of which nitric oxide (NO) is important constituent is a free radical gas which is synthesized by nitric oxide synthase (NOS).NO inhibits DNA synthesis and can damage DNA directly by deamination. In this study, NO level was studied in normal, pre- and postoperative cases of breast carcinoma. For this blood samples from 60 breast carcinoma cases were taken along …
